Arrays, arrays, everywhere arrays!

The 4th graders in our class have been studying arrays and how we use them and see them everyway!
Do you know what an array is? I bet you do and didn't even know it! Check out some of the arrays the 4th graders found just in our room!

5th graders worked with building arrays last year. Now they are working on indentifying characteristics of numbers such as prime, composite and square.

Both are pictures of the 5th graders discovering why certain numbers are called square numbers.

Can you?
